A child, who is holding the water gun in a horizontal position 40 degrees incline at a constant speed of 5m/s. The child fires the gun 1m above the ground and the water takes 0.5s to reach the ground, how far will the water travel horizontally?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
